What are the advantages of weeds?

An ability to settle quickly in, take over and spread throughout a space are advantages of weeds. Weeds seed and settle in just as quickly as they can be uprooted. In equally quick fashion, they take over a space. They do so through their ability to survive in harsh conditions that cripple or kill other plants. And in similarly quick ways, they spread from the space in which they start to just about every space that they can spread their roots and their seeds into.
